Napoli coach Walter Mazzarri rates Roberto Mancini's Manchester City among the best in the world.

Mancini said last week that he believes his team are now playing at a level equal to Barcelona and Real Madrid.

Mazzarri told the Daily Mail: "I agree with Mancini and his assessment.

"His team are up there now with Barcelona, Real and Bayern Munich. They are wonderful team.

"I watched the game against Newcastle in the Premier League. They walked through it.

"There is so much quality on that pitch when they play and I think they could beat anybody they wanted."
